such as will enable others skilled in the art 1 to which it appertains to make and use the same.

This invention relates to a new and improved device primarily intended for the purpose of stretching the wires of fences.

The principal object of the invention is to generally improve the construction and operation of the specified device for any of its wagon jack or post puller, which willbe fully described hereinafter and afterward specifically claimed.

In order that the construction and operation thereof may be readily comprehended, we will now proceed to fully describe our invention in connection with the accompanying drawings, which illustrate approved embodiments thereof, and in whichdrawings,

Figure 1 represents in side elevation, a fence wire stretcher constructed in accordance with our invention, in position for use. Fig. 2 represents a transverse sectional view taken on the plane indicated by thebroken' line 2-2 of Fig. 1.' Fig. 3represents a sectional view taken on the plane indicated by the broken line 33 of Fig. 1. Fig. at represents the pawl lever and pawl, in inside elevation, detached from the machine, the handle end being broken away.

Like reference characters mark the same parts wherever they occur in a the figures of the drawings.

Referring to the drawings in general terms, 10 indicates a tree, post, or other fixed object to which our improved fence wire stretcher is to be attached, by chains 11, or in any other suitable manner, said chains connecting with the main body 12 of the stretcher, upon which is mounted the slide 13, which in turn is connected by chains 14. with brackets 15 attached to a clamp 16, for

plurality of grasping and holding the wires 17 of a fence.

The main body 12 is provided withteeth 18 on one edge and similar teeth 19 on the 0pposite edge, and is longitudinally and centrally slotted'at 20, which slot may or may not run through the clamp end ofthe main body but when it does run through, a plate 21 will be secured to the two branches of the body'by bolts 22,or other suitable fastenings. The slide 13 is mounted, as before stated, on the main body 12 and consists of a plate' on each side of the body, securedtogether by rivets 23 which pass through the slot 20 of the body, andrivets 24, which pass through the two plates of the slide outside of the edges of the body and far enough away therefrom not to interfere with or engage the teeth 18. 1

On one side of the main body 12, between said body and one of the plates of the slide 13 and pivotally mounted on a rivet or bolt 25 which connects the two plates of the slide and passing through the slot 20 of the main body, is a pawl lever 26. This pawl lever on itsouter end carries a pivoted pawl 27 ,connected by a link 28 with a cross 29 pivotally mounted on a pin 30, which is slidable in the slot 31 in thepawl lever and is normally pressed inward toward the main body by a spring 32 coiled around a rod 33,

and arranged to normally press said rod and the pin 30 toward the main body. The

spring 32 bears at one end against a lug34, securedto the pawl lever, and at the other end against a nut or collar 35 'on the rod33 said rod being pivotally connectedat 36 to a handle bar. 37, pivoted at ,38 tothe pawl lever. At .the opposite end from the link 28, the cross bar .29 is connected by a link 39 with a pawl 10, pivot-ally connected to the pawl lever, the pawls 27 and iO normally moving of the slide on the main body would held in yielding engagement with the teeth 18 and 19, respectively, of the body, by the yielding pressure of the cross bar 29 inward toward the main body, as will clearly appear. The slide 13 being connected by the chain It with the clamp, when said slide is operated in the direction tothe right, as illustrated in Fig. 1, said chain and clamp are both pulled to the right, carrying the wires with them and thoroughly stretching them.

The slideis moved toward the right by oscillating the pawl lever 26, as follows: In their normal position the pawls 27, and 40, as before stated, yieldingly engage with the teeth on the opposite sides of the body 12. When the handle end of the pawl lever is moved, say to theright, the point of engagement of the pawl 27 with the teeth 18 will become the fulcrum and the pawl lever will oscillate on the pivot of that pawl, carrying the central pivot 25 of the pawl-lever along in the slot 20 and sliding the pawl 40 over the teeth 19. When the end of this movement of the pawl lever to the right is reached, by moving said lever to the left, the pawl 40 becomes the fulcrum and the lever will oscillate on the pivot of that pawl and slide the pawl 27'over the teeth 18 to take a new hold. When it is desired to remove the pawls from contact with the teeth, the handle bar 37 is pressed toward the pawl lever which will draw'outwardly on the rod 33, drawing the cross bar 29 outward and directly pulling the pawl 40 out of engagement with the teeth 19 and indirectly, through the link 28, tilting the pawl 27 on its pivot, out of contact with the teeth 18. The slide can now be moved in either direction on the main body, this provision of free movement being necessary in order to set the slide in the beginning of the operation, the slide and pawl lever being carried together in the sliding movement by reason of their connection by the rivet or bolt 25 which passes through the slot 20, as before de scribed. With the body 12 secured upon a post or tree 10 and the slide moving thereon in the manner described and carrying the clamp with it, the operation of stretching wires will be obvious. It will be observed that the slide 13 projects to one side of the attached slide may be set up vertically on the ground or a floor, resting on the plate 21 which would then become the base, when by inserting the rejecting portion of the slide under the axlie of a vehicle, the described raise the axle or other portion of the vehicle off-the ground, the device in this case become ing a wagon jack, without altering any of its working parts.

The manner in which the device may be utilized as a post puller will be identical with the manner of its use as a wagon jack with the single exception that chains similar to the chains 14 may be connected with the slide to engage around the post.

\Vhile we have specifically described the construction, operation and arrangement of the various parts comprised in our invention, it will be obvious that changes and variatiens may be made therein within reasonable limits, without departing from the spirit and scope of the invention.

Having thus fully described our invention, what we claim and desire to secure by Let ters Patent of the United States is 1. In a. device of the character described, a main body toothed on its opposite edges and provided with a central longitudinal slot, a slide mounted on the body comprising plates on the sides thereof connected by bolts passing through said plates and the slot of the body, a pawl lever pivotally mounted on one of said connecting bolts, pawls pivotally mounted on said pawl lever on opposite sides of the body, means for holding said pawls yieldingly in contact with the series of teeth on the opposite sides of the bodv. said means comprising a cross bar longitudinally and pivotally movable with respect to the pawl lever, links connecting said pawls separately with said cross bar, and means for normally holding said cross bar toward the body.
